Development of a Test Procedure for External Domestic Hot Water Modules

The market of domestic hot water modules (DHWM) is growing fast, but the absence of a standardized testing procedure makes comparison of the products and quality assessment difficult. Therefore a project is being carried out at SPF aiming at the definition of a test procedure for DHWM. In the first phase a suitable test rig has been set up and six commercially available modules where tested extensively. In this paper, an overview over the results of the first testing phase is given, focusing on three main performance indicators: power, comfort and efficiency.
